N-600 Certificate of Citizenship
Helping Individuals Prove U.S. Citizenship Through Parents
Some people are already U.S. citizens through a parent but need legal documentation to prove it. Form N-600, Application for Certificate of Citizenship, may be used by certain individuals who acquired or derived U.S. citizenship through a U.S. citizen parent.
At Kanu & Associates, P.C., we help clients in Arizona and New Mexico evaluate possible citizenship claims and prepare N-600 applications with careful attention to eligibility, family history, immigration records, and supporting evidence.
Why an N-600 Application Matters
A Certificate of Citizenship can be important for employment, passports, government benefits, immigration records, and long-term security. However, N-600 cases require careful review because USCIS may examine the applicant’s birth records, parent’s citizenship, custody history, lawful permanent residence, residence with the parent, and other legal requirements.
Filing without proper review can create problems, especially if the person’s immigration history or family records are incomplete.
